| OSI model is a 'reference model' that describes how the protocols should interact with each one another invented by the Department of Defense. Where as TCP/IP model becomes one of the standards that enabled the Internet what it is today.. the application layer of TCP/IP model can handle the resoponsibiltes of the layers 5,6,7 in OSI model. The transport layer in TCP/IP does not always guarantee reliable delivery of packets at the transport layer, while the OSI model does. TCP/IP also offers an option called UDP that does not guarantee reliable packet delivery. |
